Target group

Very preterm and particularly extremely preterm infants, small for gestational age infants, and parents

User group

Healthcare professionals, neonatal units, hospitals, and health services

Statement of standard

Bronchopulmonary Dysplasia (BPD) is prevented using evidence-based strategies including avoiding mechanical ventilation, minimally invasive administration of exogenous surfactant, volume targeted ventilation and early caffeine, and administration of systemic steroids in infants still requiring ventilation during their second postnatal week.

Rationale

Bronchopulmonary Dysplasia BPD results from the effects of non-physiologic stimuli (e.g. inflammation, ventilator induced lung injury, high supplemental oxygen levels) in an infant with underdeveloped lungs and defence mechanisms (e.g. anti-oxidant capacity). (1) Interventions that reduce inflammation (e.g. steroids) or any of these non-physiologic stimuli (e.g. mechanical ventilation) are likely to reduce BPD rates. Some of these interventions may additionally promote the survival of the target group; none decreases the chances of survival. (2)

BPD, defined as supplemental oxygen requirement at 36 weeks post-menstrual age, is a risk factor for later respiratory hospitalisation in infancy, compromised lung function in childhood, neurodevelopmental impairment, and a potential risk factor for chronic obstructive pulmonary disease in later life. (1,3)

Benefits

Short-term benefits

Reduced risk of BPD by avoiding invasive mechanical ventilation (risk ratio (RR), 0.91; 95% Confidence Interval 0.84-0.99) (2)
Reduced risk of BPD by use of minimally invasive surfactant administration (RR 0.75; 0.59-0.94) (4,5)
Reduced risk of BPD by use of volume targeted ventilation (as opposed to pressure targeting) (RR 0.61; 0.46-0.82) (6)
Reduced risk of BPD by starting caffeine on postnatal day one or two instead of later (RR 0.51; 0.40-0.64) (7,8)
Reduced risk of BPD by administration of vitamin A intramuscularly for the first four postnatal weeks (RR 0.87; 0.77-0.98) (9)
Reduced rate of death or BPD by administration of systemic steroids in ventilated infants (RR 0.72; 0.63-0.82) without increasing the risks of cerebral palsy (10)

Long-term benefits

Reduced adverse neurodevelopmental outcome if BPD can be prevented (3)

A (High quality)

Patient information sheet¹

For healthcare professionals

A unit guideline on the management and prevention BPD is adhered to by all healthcare professionals, and includes the following advice:
- Surfactant is administered via a thin intra-tracheal catheter if FiO₂ is >0.30 or using INSURE (intubate surfactant extubate). (11)
- Volume targeted ventilation (at 5-7 ml/kg) is used plus adequate PEEP level, if intubation cannot be avoided. (6)
- Infants on n-CPAP are switched to synchronised nasal ventilation if respiratory distress visible while on CPAP. (12)
- Caffeine is administered from day 1-2 after birth (10 mg/kg loading, 5 mg/kg/d maintenance for caffeine base). (7,8)
- Vitamin A is considered (5000 IE i.m. three times/week for week 1-4 after birth). (9)
- If mechanical ventilation is still necessary during postnatal week 2, postnatal steroid use is considered (dexamethasone at the lowest effective dose possible. (13,14))
- Efforts to reduce rates of nosocomial infection, as a risk factor for BPD, are made. (15)

For healthcare professionals

Investigate in larger numbers whether using synchronised nasal ventilation rather than CPAP is the preferred mode of nasal respiratory support. (6)

A (Moderate quality)

Evaluate alternative anti-inflammatory strategies, e.g. hydrocortisone, inhaled budesonide, or tracheal instillation of budesonide together with exogenous surfactant to generate more data on their long-term effectiveness and safety. (10,16,17)

A (High quality)

Investigate the role of eradicating Ureaplasma urealyticum shortly after birth. (18)

A (Moderate quality)

Investigate oral Vitamin A administration as well as the role of other nutrients. (9,19)

Find the optimal drug and dose for postnatal steroid application. (9)

Getting started

Initial steps

For parents and family

Parents are verbally informed by healthcare professionals about BPD and strategies to minimise its risk. (1)

For healthcare professionals

Attend training on management and prevention of BPD.
Apply exogenous surfactant via less/minimally invasive administration via a thin catheter, i.e. without using an endotracheal tube, or via the INSURE method (intubate, surfactant, extubate).
Use nasal continuous positive airway pressure (n-CPAP) instead of intubation and mechanical ventilation. (22)
Start caffeine on postnatal day 1 or 2 instead of later.

For neonatal unit

Develop and implement a unit guideline on management and prevention of BPD.
Develop information material about BPD for parents.

For hospital

Support healthcare professionals to participate in training on management and prevention BPD.

For health service

Develop and implement a national guideline on management and prevention of BPD.
